We divide 78415583 by 151
The aim is to understand the frequency of 151 in 78415583.

Advancing to step 1:
When dividing 7 by 151, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 151

Step 2:
When dividing 78 by 151, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 151

Step 3:
151 goes into 784 5 times with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 755 from 784 leaves us with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 151

Step 4:
When dividing 291 by 151, we get 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 151 from 291 and we're left with 140.
Include the next digit (5) from the dividend after 140, then repeat: 1405 / 151

Moving on to step 5:
If we divide 1405 by 151, we get 9 and a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 519.0
If we take 1359 away from 1405, we end up with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 151

Advancing to step 6:
151 can be fit into 465 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 5193.0
If we take 453 away from 465, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 151

Advancing to step 7:
If we divide 128 by 151, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 51930.0
Subtracting 0 from 128 leaves us with 128.
Append the next digit (3) from the dividend to 128 and continue with: 1283 / 151

Step 8:
151 can be fit into 1283 8 times, resulting in a remainder of 75.
The next digit of our result is 8. 
Result so far: 519308.0
Subtract 1208 from 1283 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
750 divided by 151 is 4 with a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 519308.4
Subtract 604 from 750 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
When dividing 1460 by 151, we get 9 with a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 519308.49
Deduct 1359 from 1460 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 11:
If we divide 1010 by 151, we get 6 and a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 519308.496
Deduct 906 from 1010 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 12:
The number 151 fits into 1040 6 times, leaving a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 519308.4966
If we take 906 away from 1040, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 519308.4966 and a remainder of 0.00134.
